ONVIF® is the global standard for integrating IP security devices into a unified system. The standard ensures seamless communication between video cameras, NVRs, video management systems (VMS) platforms, and other security solutions, regardless of the manufacturer. Previously, an Ajax system allowed connecting third-party cameras, but now Ajax video devices are ONVIF® Profile S and Profile G conformant. This means that you can now integrate Ajax video devices with the existing infrastructure.
ONVIF® groups its standards into profiles that cover different needs:
Profile S for basic video streaming and recording.
Profile G accessing, searching, playing back, and managing recordings stored on video devices.
Profile T for access to advanced video streaming features, such as H.265 compression.
Profile M for metadata and analytics event transmission, including AI recognition.
Profile A for access control.
Ajax video devices are ONVIF® Profile S conformant, which enables RTSP-based video and audio streaming, as well as H.264 encoding for video compression.
Ajax wired cameras and NVRs are also ONVIF® Profile G conformant. This allows third-party VMS platforms or NVRs conformant with ONVIF® Profile G to access and retrieve stored video and audio, search for recordings by time, remotely play back recordings stored on Ajax cameras or NVRs, and configure or control recording sessions.
Ajax video devices implement ONVIF® H.2651 (HEVC) encoding, transmission of motion detection and AI recognition events, control over Wide Dynamic Range (WDR), and other image settings — not ONVIF® profile or add-on conformant.
All the aforementioned functionality allows you to integrate Ajax video devices with VMSs such as Milestone, Genetec, Axxon, and Digifort.
¹ For video devices that support the H.265 video codec.
Ajax video devices operating within an Ajax system use passwordless authentication and proprietary video streaming. Authentication via Ajax Cloud ensures reliable protection of all sensitive data. When you use an Ajax video surveillance system, we strongly recommend connecting all devices directly to Ajax Cloud via our apps.
When ONVIF® is enabled, potential risks of data vulnerability arise:
Connecting an Ajax video device to a third-party VMS via ONVIF® requires bypassing Ajax Cloud.
The login and password of each user with access to the video stream can be a weak spot.
If you connect Ajax video devices via ONVIF®, please keep passwords secure.

How to configure a connection via ONVIF
To configure ONVIF® connection for Ajax video devices:
Open an Ajax app.
Log in to your account or create a new one.
Select a space or create a new one.
Add the required Ajax video devices to the space. You can find detailed information in the user manual of the respective device.
Go to the Devices
tab.
Select the video device you want to connect via ONVIF®.
Go to its Settings
.
Select Service settings.
Click Connection via ONVIF.
Enable the Allow ONVIF integration toggle.
Select the setup method:
Setup in wizard;
Use default settings.
If you select Setup in wizard, you can specify all the necessary settings, such as network, users, etc., step by step.
Please create strong passwords and keep them secure to reduce the risk of data vulnerability.
If you select Use default settings, the default network settings are applied:
Connection type: DHCP.
ONVIF port: 8080.
RTSP port: 8554.
You can change the default network settings at any moment.
Add at least one user, specify their role, and enter a username and password.
If you plan to use a connection via RTSP, copy RTSP links from the Mainstream and Substream fields.
To access a video stream from the selected device in third-party systems, replace placeholders in provided links with actual credentials.
How to change ONVIF user settings
In an Ajax app, select a space with a video device whose ONVIF user settings you want to change.
